Topic: VPN between e-smith servers

[Xavier]

i have 3 offices. in 2 of them e-smith server and gateway is connected to internet via adsl and it works fine (workstation are nt40). In the third office  (internet via specialized line ) i have a firewall (sonicwall) protected the local network. all my internet servers are in the DMZ of the firewall. a e-smith-server is connected directly to internet (another address from the firewall)  
i want the users of the  offices come in the each local network via VPN
is it possible to do that ? and how
can a e-smith server be a VPN client to another ?
 
merci

Sorry for all other people, the answer is in french.

"Il suffit dans la page de configuration "remote access" de remplacer le 0
pour "Number of PPTP clients" par le nombre de connexions simultanées que tu
souhaites.
Ensuite sous le poste a partir du quel tu veux te connecter de créer une
connection VPN. L'adresse de l'hote est l'adresse IP internet de ton serveur
VPN. Pour se loguer, il faut utiliser un utilisateur éxistant sous e-smith."

Translation :
"In the "remote access" configuration page, your must replace the "0" value for "Number of PPTP clients" with the desired number of simultaneous client connexions.
Thenon the station you want to connect from, your must create a VPN connexion.  The host address will be the internet (external) IP address of your VPN server.  You must use an existing e-smith account to log in."

Now my idea about this :
This seems like the way to connect from workstation A on site 1 to the local network on site 2.
I suppose that if one wants a transparent configuration, some sort of tunnel is created between the 2 VPN servers, and they have routing tables allowing them to route through the tunnel, to the internet or to the lan, according to the packet destination.
Now don't ask me HOW to do this  I'm just a poor MCSE !
